There is also libffi (which has been merged into gcc, I think, but

about it. At first glance, it doesn't look so good (I can't tell
whether it works on Windows, and it's definitely missing variadic
functions and bitfields and maybe callbacks).

Libffi works on Windows. Bitfields and callbacks are fine. Variadic
functions is an interesting point, but AFAICR no ABI I use treats them
any differently from functions with fixed arity. Does Windows? I
can't remember.

Ah, so it just has poor/outdated documentation. That's not so bad.

I remember having some trouble with OSX/PPC with variadic something, but
it was probably the ioctl syscall, not regular function calls.

Thanks for the clarifications, everybody.
